The practice of science communication is fundamentally changing. This requires science communication practitioners to continuously adapt their practice to an ever-changing ecosystem and highlights the importance of reflective practice for science communication. In this study, we supported 21 science communication practitioners in developing a reflective practice. Our study shows that reflective practice enabled practitioners in becoming aware of their own stance towards science or assumptions regarding audiences (single-loop learning), underlying and sometimes conflicting values or worldviews present in science communication situations (double-loop learning), and facilitated practitioners to adapt their practice accordingly. Triple-loop learning, allowing practitioners to fundamentally rethink and transform their mode of science communication, was less observed. We argue that reflective practice contributes to opening-up public conversations on science — including a conversation on underlying values, worldviews, and emotions, next to communicating scientific facts.

In the wake of the technical development of our era we are increasingly faced with claims of extremely large amounts. Whereas even in the past century large claims were mostly due to elemental or natural forces such as earthquakes, hurricanes and floods, there are today other causes, conditioned by human factors, that have considerably increased in importance. Another fact to be observed is that the risks that are passed on to the insurance market assume a more serious character year by year. Large building complexes, giant tankers, containers, atomic power stations, dams and jumbo jets pose for the insurers problems which are in no way easy to solve, since the risk covers required touch the limits of market capacity and their rating is subject to great uncertainties. At the same time, the readiness to underwrite such covers is a matter of utmost importance for the private insurance industry. For the coverage of such large risks, various insurance forms have been developed in the past years within the range of non-proportional methods. Besides the excess of loss and stop loss covers in their usual form, the cumulative loss cover and the largest claim cover have attracted particular attention. The cumulative risk cover has, for example, been dealt with in [11]) and has also been frequently offered in practice. The coverage of the largest claim or, more generally, of the sum of the n largest claims does not appear to have gained a proper foothold in practice in spite of various valuable contributions in this field—considering particularly [2], [3], [5], [8] and [14]. The fact that it was during 1963/64 that various authors analysed these problems is no coincidence, for it was then that in two ASTIN Colloquia these topics were discussed

The response to the invitation for the 5th Colloquium has been, especially for subject 1, very gratifying; a large number of meritorious papers have been sent in. Fortunately, it took not much time in this case to find a good guide for all this work. R. E. Beard presents in his article "Some Actuarial Aspects of Non-Life Insurance Company Management”) a broad cross-section of the many problems that confront the non-life insurer. It was therefore regarded as not quite unwise to follow his steps and to discuss the other papers at suitable points. In the first half of his work R. E. Beard deals with a practical example from motor insurance, which is fully calculated with the help of numerical data. The question relates to the estimation of the value of outstanding claims, a quantity which is of decisive importance for the evaluation of the results of a portfolio. Apart from chance fluctuations which might affect the statistics from year to year, there are three major factors that render the task of estimation difficult: (a) the natural growth of the portfolio (b) the fact that bigger claims require longer time for settlement than the smaller ones (c) the change in the value of money with time
